The Baena Detour: A Simple Baked Spider Crab Recipe for One

I went to the DIY store in Baena for six screws and came back with a medium-large spider crab. That is the beauty of living near a Spanish market; you never know what the fishmonger has tucked away, and today it was the perfect excuse to whip up a baked spider crab recipe for lunch.

For those travelling through the region in a campervan, Baena is a fantastic stop. Even though I live just over the border in Jaén province, I often nip across to Córdoba to take advantage of the local amenities. A new área de autocaravanas has been built there, handily located right next door to Lidl. It’s a practical spot to park up, but the real magic happens when you wander away from the supermarket and towards the local indoor market stalls.

The Liquid Gold of Tucci

You cannot cook in this part of the world without acknowledging the olive oil. While the neighbouring Baena is world-famous for its Denominación de Origen, my kitchen runs on the "verde" from Montetucci. Produced right here in my village of Monte Lope-Álvarez, this oil carries the weight of history.

Martos was known to the Romans as Tucci (Augusta Gemella Tuccitana), and the oil produced from these ancient groves is remarkably bright and peppery. Using an oil with such deep Iberian roots to sauté your aromatics isn’t just a choice—it’s a nod to the heritage of the land I now call home. Even 160km from the coast, this liquid gold is the perfect partner for fresh seafood.

A Basque Love Affair with Seafood

While I found my crab in the south, this preparation is a nod to the north. The Basques have a legendary obsession with the sea, and their seafood cookery is arguably the finest in Europe. They treat ingredients like the centollo (spider crab) with immense respect, often stuffing the shells to create Txangurro. It is a culture that celebrates the ritual of "picking" at shellfish—a slow, resourceful way of eating that fits perfectly with a quiet afternoon on the terrace.

A Traditional Basque Baked Spider Crab Recipe (Centollo al Horno)

This "for one" version of a baked spider crab recipe is a simplified take on the classic. It’s resourceful and slightly messy to prepare, but incredibly rewarding to eat straight from the shell.

The Prep: Boil the crab in heavily salted water (30g salt per litre works well) for about 15 minutes. Let it cool, then pick every scrap of meat from the legs and the body. Clean the top shell (the carro) and set it aside to use as your baking dish.

The Filling: Finely dice a small shallot and a bit of leek. Sauté them in a generous glug of Montetucci olive oil until soft. This oil comes from my village—Monte Lope-Álvarez (near Martos)—and using it feels right. Martos was the ancient Roman city of Tucci, and even though I’m cooking this 160km from the coast, the rich, inland soil of the olive groves is the perfect partner for the sweetness of the crab. Stir in the picked crab meat, a splash of brandy (flamed if you're feeling brave), and a tablespoon of tomato frito. Add a touch of fish stock if the filling needs more moisture before baking.

The Bake: Pack the mixture back into the cleaned shell. Sprinkle with a few breadcrumbs and a dot of butter. Bake at 200°C for 10 minutes until the top is golden and bubbling.
